Llamasoft does TxK for Sony Vita

[gilesgoat]

And now that I found a NASTY ( again, very silly ONE line of code ) bug in a "demo code" that was causing "wild memory corruption" ( reported to them ) I feel I can really go and enjoy the curry

Why it does not happen in the "demo" program I don't know but it was managing to "blast" the "particles generator" with "just the right mem corruption in the right place" by "simply" doing a free() twice with an address that was already freed.

But now CURRY CURRY !

Having just seen this http://minotaurproject.co.uk/YakImages/moo.mp4 I'm really rather liking the pyramid background ... works really nice :-) and this is just beautiful :-) http://minotaurproject.co.uk/YakImages/tit.mp4

Just tried to view moo on my PS Vita.

The browser only gives you the option to save the video file (rather than just stream it), so I save it, but then when I play it in Videos it's choppy as fuck.

Same here. The earlier one didn't look a smooth as it might be either.

The resolution seems to be much higher than that of the Vita screen though so maybe a native res file will play a lot smoother?

NO ... wait a sec .. unless Jeff made some scaling I am not aware of that thing is "AS IT COMES OUT FROM THE PS VITA !"
literally grabbed with ah ( moderately expensive ) capture device connected to the PS Vita devkit.

It's a capture made in H.268 format converted into MP4, the "original capture" sure plays quite smooth but it also is
a few GBytes long.

I am not sure if I am allowed to say or if it's an NDA so I won't say it however the res of the PS Vita is "not that small and not that big".

I don't think that capture is "much higer".

the res of the PS Vita is "not that small and not that big"

I have no NDA restrictions.

960 x 544

*ahem* allegedly *ahem*

Wikipedia agrees.

moo.mp4 is 1280 x 720.

Internal screen buffers don't have to same as the output device rez

Thing is, if I download it on my PC and view it in any media player, it's really smooth.

It's also smooth if I use the Vita's wifi streaming from the video file I saved on my PC.

It just plays juddery on the Vita if I click the link then save and view.

I've downloaded both moo & tit and played them in the latest version of VLC and can confirm that there is a degree of judderiness in them both.

A multi-threaded race condition perhaps? Thread A free()'s the memory and NULLs it, Thread B writes to that same memory, second call to free() in Thread A wipes it again since it's not NULL anymore (assumes you kept the pointer address around), and then Thread B crashes since now it's NULL.

Regardless, curry earned.

Nah nothing that sophisitcated, it was a state machine that at the end of a certain operation it was passing by an "end" state, if an error was present it was opening
an error dialog but at the pressure of "OK" it was returning once more into that "end" state, the if (mem) free (mem) should have in fact "do nothing" in that case but
they forgot to put the mem=NULL; after free.

Nothing "super special".

Besides it's Saturday and we are still working, the show must go on ..

I bet that looks lovely moving.

The native res of the screen is indeed 960x544, a lot of games seem to render at 848x480ish and scale up, the mini hdmi out on the dev units scales to 1280x720 as the HDMI spec does not support 960x544

What is interesting here though, is that they chose the option to scale to fill the frame, yet the PSP component and VGA outputs (both consumer and dev devices) just rendered the 480x272 framebuffer unscaled in the center of a 640x480 vga timing frame wasting a lot of the screen, but maintaining the same detail.

Anyway, I really wanted them to add the hdmi out on the retail units, as it looked pretty decent even when doing internal demos and running it through a projector, but I could see a situation where the next monster hunter, or successful equivalent, came out and noone in Japan would ever buy a home console, as they would have a portable device that would look great at home plugged into the tv

If I really want to be "really really picky" I could say that "compared to the AMAZING PS Vita screen" you really see the scaling when attaching to an HDMI output.

So it's like yes BUT there's a bit of filtering/blur going on that effectively makes you LOOSE a bit of sharpness/detail ( compared to the screen ).

Even if still pretty nice if I'd be looking for "the mega perfection" I could/would say that "I don't really know if you really want the HDMI output" MAYBE it could
be interesting to see how it would look "letterboxed" in native res into a 1280x720 frame.

Also is not "super super practical" I mean this "little thing" in your hand connected to a cable/connector ( the HDMI one ) which is NOT "very studry" makes me
feel a bit "if I accidentally waggle this thing while playing I am going to rip off connector and PS Vita probably".

So in fully honesty "yes nice for some demo" but practically I can't see really "a way to go" to connect a PS Vita via HDMI to a TV, "at best" then you have have some
wireless controller you use to control the Vita itself leaving it just "flat down on somewhere connected to the TV" that MAYBE could be more acceptable.

But "playing with the Vita and and HDMI cable connected to a screen" .. I don't think so ... plus the connector is "on the wrong side", it should be the other side.

It's a super lovely portable device I'd say but not really designed to be connected to a TV.

In that case, to begin with I think you'd really need a native 1280x720 and a few other modifications.

Giles - that's a *whole* lot of "finger quotes".

I think they'll soon invent/apply a "quote filter" for my posts
